i Application filed May 9, 1917. Serial No. 167,492.

To all 'whom t may concern:

Be it known that I, JACOB O. HART, a

citizenl of the United States, residing at Lancaster, in the county of Lancaster and State `of Pennsylvania, have invented certain new and useful Improvements in Carriers, of which the following is a specification, reference being had to the accompanying diawings. i i

This invention relates to certainimprovements in carriers, and has relation more particularly to a device of this general character especially adapted for use in rural districts for transporting mail between a dwelling and highway; and it is an object of the invention to provide a novel and improved means whereby the operating means for the carrier proper may be employed in connection with an indicator, in order to show at one end of the line of travel of the carrier when mail or the like has been deposited in 4the `carrier at the opposite endof the line.

Furthermore it is an object of the invention to provide a device of this general character with novel and improved means whereby the operating means for vthe carrier `proper is conveniently and effectively maintained in applied` position and'whereby the carrier proper is permitted to travel with facility.

`The invention consists inthei details of construction and in the combination and arrangement of the several parts of my 1m- Yproved carrier whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel featuresl of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to de-I scribe the same with reference to the accompanying drawings; wherein- Figure l'is a View in side elevation illustrating a carrier transmission constructed in accordance with an embodiment` of my invention;

Fig. Q isa fragmentary view in elevation of one of the intermediate stationary supports; f V

Fig. 3 is a fragmentary view in top plan m at the dwelling end of the apparatus; n

Fig. 4 isan enlargedelevational view of the clamp as-herein provided; and

Fig. 5 is a view partly in end elevation and partly in section ofthe clamp as herein embodied. i

As disclosed in the accompanying drawings, 1 denotes a stationarysupport adapted to be positioned adjacent a dwelling or the like, and 2 denotes a second stationary support adapted to be positioned adjacent the highway. Intermediate the supports l and 2 are additional stationary supports 3, of any number required by thel necessities of practice. Rotatably supported by the support l and about a horizontal aXis is a double sheave or pulley t. The. support 2 rotatably supports the single sheave or pulley 5 also mounted upon a horizontal axis.

C denotes the carrier proper, which is.

preferably cylindrical in form and having its opposite end portions conical. The upper wall of the carrier C is provided with a door 6, to facilitate the insertion or removal of mail or the ,like therein. The forward end portion of the carrier C is provided with a guideway 7 adapted to receive a. slide 8. The slide 8 is provided with suitable means to indicate to the mail man that the carrier C contains mail matter to be collected.

Secured to the opposite extremities of the carrier C are the flexible members F and M. The member F is adapted to be wound around the sheave or pulley 4 within one of the grooves therein, and said member F is suitably anchored within said groove. The second member M is disposed around the second pulley or sheave 5 and is then returned to the sheave or pulley 4 and adapted to be wound therearound in the second ,tendency to materially aifect the successful operation of the device.

When it is desired to cause the carrier C to travel to thehighway it is only necessary to impart the necessary rotation to the sheave or pulley lt, Aand 'as herein disclosed, said pulleyor slieave is provided with an operating? crank 10.- Howevei, I donotwlshK to be understood as limiting myself to this particular means of. rotating lthe sheave. or`

pulley et, as any other means may be used which can be employed with convenience and facility.

In Eits travel toward the highwayoixtof, ward the dwelling, the carrier C is adapted to pass through the rigid `loop members 11` extending upwardly fromlthe tops of the intermediate supports 3,' and through which upstanding lloop members 11 the flexible members Fand M are alsoadapted to travel. It willV be at once self-evident thatby this means, the upper stretches of the members F and M, or those stretches of the members directly connected to the carrier C, are also p i'evented Ifrom sagging. To facilitate the passage of the carrier C' through the loop members 11, I'find it'of` particular advantage to intersect the lower portion of said loop .members with theaiitifriction member-S12, herein disclosedas rollers rotatably mounted vupon the upper ends of the supports 3 proper.

suitably formed `on the side `face of, the

pulley or` sheave is anindex 14, herein disclosed as iii the simulation of 'an arrow;

yand A'when said arrow; is disposed upwardly and substantially vertical it giyesiindication that mail, h as been deposited withinthe carrier C at the highway. 1nassembling the 'device,`the sheave or ,pulley 4 is so adjusted tobause the index lt to be. positioned be yond the vertical when the carrier C is at the limit of its movement ielativeto the highway. A fter themail man has deposited matter within the carrier C itis onlynecesf sary forhim to imparta slightoutward movement to the lower stretch of .the inember M, to ca use the index 14 to assume the desired yvertical position. VAt this .tiinejit might be well testate that the index 1 4 yis preferably disposed radially oftliegsheave ork pulley t. The index leis also adaptedto indicate when lthe mail carrieirlias .leftat thekroad side aparcelvvof a sizetoo large to be deposited witliin the carrier C. In this event, further 4pull'jis imparted to thelower stretch'of the memberA M to cause the l.index to point downwardly. To' facilitate the movement of the lower stretch ofthe ineinber M, I find it. of fad- Avantage to pivotally engage with the support 2, la lever 15 co-acting with a Vclamp 1`6 adapted to bedetachably engaged with thelowernstretcli of theineinber M, wherevby" the' requisite pull. I.or pulls may be 'iniparted thereto for causing the partial -rotation of the ypulley or sheavec toibriiig; the "index 14C into one .of its indicative positions. A s this is particularly illustrated `in Fig. y{1,the clamplG comprises crossed ineinlfbers' 17 pivotally connected one Vwith the other. .Corresponding enls,.ofthe members 17 lhave pivotallyengaged therewith, rigid links 18 which are also pivo-tally engaged .witlitherigid arm 19.. The arm 19-is pivotally engaged with the lever 15, wherel.bythe clamp 16 is caused to be moved in either will be understood that when outward movenient is imparted to the lever` 1 5, the meinbers 17 will; clamp upon-'the lower stretch of the member 'M' toA effect the Arequisite pull thereon for controlling the position offthe imparted to the lever 15, the Vmembers `17 will" separate so that theclampd'fmay'be properly positioned upon the lower"` stretch of 'the member M `to effecta second pull.

By liaving theL member M "disposed through f the loop 20,- the clamp 16 is 'atall times maintained. inoperative position relativeto theineinberl/l. will" alsolbe understood that thegloop 20 permits` an unobstructed index 14. Upon inward movementbeing travel of the lower 'stretch of themember M ltherethrough so that no `l`ii`ndran`ce or obstructionwll" be; offeredv to the movement bf the carrier C in either direction.

" :have al'sofoun'd of'advant'age to provide at the road end of my device, a buffer or stop for limitingthe movementl of the carrier toward they road. As herein embodied, the buffer or stop -coinprisesa Vflat spring 21 secured 'to the upper end portion of the post 2, and disposed inwardly "onsuch" "inclination, as to intersect the travel 'of the upper stretch of the member 1 and terminating a slight distanceiinwardlyof the sheave or pulley 5: Asher'einembodied, the upper `stretch'of theine'mberM` is loosely disposed vthroughthe free extremity of the 21.

From the foregoing description, "it is thought to `be obvious that acarrierfcon- `structed-in accordancewith my invention is ofan extremely 'simple vandcompara# tively inexpensive lnature"'and 'is particularly well adaptedfor use by reason of the convenience andl facility with'whi'ch itlniay be assembled; and itl will alsofbe obvious that my invention Ais susceptible ofsome" change and modification "without material departure from the `principles andspirlit tliereof,"and 'for'this reason Ido not wish to be understood aslimiting myselfrtothe precise arrangement and `formationof the l severalparts herein shown in` carrying out my invention in practice, except. as hereinafter claimed.

Having thus fully described my invention,

what l desire to claim and secure by Letters-Patent, is:
